Curious to to know...

Why would one choose RaceChip over a BMS JB4?

Racechip is cheaper and doesn’t need to connect to the obd port. Racechip is easier to install.

JB4 has more features. JB4 app can change maps, can display diff readings like boost, can log, and can read/clear error codes. I think Racechip just changes maps.
